[Scaffolding Construction Achievements] Himi Yume Bridge

Thank you for using the repair work on the Hirabayashi Bridge on the Nagasaki Expressway.

We would like to introduce our construction achievements at the Hirakawa Dream Big Bridge. For the side span, we adopted a method using rack scaffolding that minimizes traffic restrictions on the intersecting general national and prefectural roads by "extending the scaffolding using rails to quickly install full suspended scaffolding." In the central span, we utilized rack scaffolding as a standard "lateral movement suspended scaffolding." Additionally, due to the limited number of suspension points, we were able to efficiently carry out the installation of fall prevention sheets on the underside of the main girder. Furthermore, since the suspension points of the scaffolding consist only of web suspension pieces, we were able to eliminate the need for anchor installation on the bridge superstructure. 【Overview】 ■ Location/Prefecture: Nagasaki Prefecture ■ Client: West Japan Expressway Company Limited, Kyushu Branch ■ Construction Company: Mitsui Sumitomo Construction Co., Ltd., Kyushu Branch ■ Start of Use: R06.5 to R07.4 ■ Local workers' experience with rack scaffolding: First time ■ Dispatch of rack scaffolding handling instructors: Yes *For more details, please download the PDF or feel free to contact us.
